HYDRAULIC AND AUTOMATIC WASTE-VALVE FOR VESSELS.

Specification of Letters Patent.

Application filed July 31,1909. Serial No. 510,648.

To all whom, it may concern:

Be it known that I, JAMEsALLINeHAM, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Hydraulic and AutomaticWaste-Valves for Vessels, of which the following is a specification.

This invention relates to automatic waste valves for liquid containingvessels, and

conslsts in certain peculiarities of the construction, novel arrangementand operation parts thereof, as Wlll. be hereof the various inafter morefully set forth and specifically claimed. I

One of-the objects of the invention is to provide anautomatic wastevalve for vessels of various kinds, but particularly for bath-tubs,wash-basins, and sinks, which;

shall be simple and inexpensive in construction, easily attached,compact in form, durable, readily understood, operated and cleaned, andwhich will serve the function of a positive trap as well asa water seal.Another object 'is'to provide a waste valve or waste automatically at agiven pressure of liquid, and

which shall have manual means for dis-- charging all or any desiredamount of liquid from the vessel, and for the following reasons it isespecially adapted for use on bathtubs, wash-basins, and sinks: 1. Whenused in connection with a bath-tub or wash bowl,

it will cheapen the construction thereof by dispensing with the overflowopening in the tub, and the overflow chamber in the wash bowl, besidesdoing away with the necessary connections with said parts. 2. It doesaway with all'of the fouling surface contained in the overflow pipes ofbathtubs, and all the chamber of wash bowls, besides it entirely cutsoff the connection with leading from the tub or bowl, thereby avoidingall the insanitary conditions known to exist, and'to be detrimental tohealth in all of the devices that have heretofore been used for thatpurpose.

" Other objects of the invention, will be disclosed in the subjoineddescription and explanation.

In order to enable others skilled in the art to which my inventionpertains, to make and use the same, I will now proceed to die.

valve stem in the overflow the drain pipes accompanying .form in theconstruction of the valve. Fig.

4, is a detail view partly in section and partly in elevation of theupper portion of the valve casing and valve stem shown in Fig. 1,illustrating modified means for holding the valve in its closedposition. And Fig. 5, is a view of the upper'portion of the showing aknob for manually operating the same.

Like numerals of reference, refer to corresponding parts throughout thedifferent views of the drawing.

The reference numeral 10, designates a portion of a vessel which may beof any suitable kind, and has communicating with its lower portion, awaste pipe 11, to which the valve casing may be connected in anysuitable manner, but in the present instance I have shown the valvecasing 12, provided on thelower portion of one of its Walls with alateral-extension 13, which is externally screw-threaded to engage acoupling or collar 14, fitted around the outer portion of the pipe 11,which pipe is located at its outer end within the extension 13, of thevalve casing. As shown,- the valve casing 12, is provided with upper andlower compartments 15, and 16, respectively, which are divided by meansof a transverse partition '17, in which is provided a downwardly taperedopening 18, to form a seat for the correspondingly tapered valve 19,thestem 20, of which is extended through a stuffing-box 21, on the upperportion of the casing. Above the stufling-box 21, the valve stem 20, isprovided with a collar 22,011 which are located a number of detachableweights'23, used to hold the valve 19, in its seated position, until agiven degree of liquid pressure is exerted on the valve to force itupwardly, and thus automatically permit the liquid to be discharged fromthe vessel through the pipe 11, and chamber 16,

' construction of the valve,

thence through the opening 18, chamber 15,

pipe 26, leading to the sewer or other point of discharge.

The bottom of the chamber 16, is provided with an opening 27, in whichis fitted a plug. 28, which can be easily removed when access to theinterior of the valve casing is required or desired for the purposeofcleaning or repairing the parts.

In the construction above described, it is apparent that the pressure ofthe liquid contained in the vessel 10, pipe 11, and chamber 16, will beexerted upwardly against the bottom of the valve 19, and when suflicientressure is attained, to overcome'the weights 23, the valve will be movedupwardly, thus permitting the water or liquid to flow up' wardlythrough'the opening 18, in'the partition 17 and then outwardly. throughthe chamber 15, and downwardlyihrough the conduit 24, into and outthrough the pipe 26, to the sewer or other point. As the weights 23, aredetachable, it is apparent that any desired number thereof, maybe placedon the stem 20, so that the liquid pressure required to operate thevalve, may be varied. As the pipe 11, is located below the bottom of thevessel, and as the outlet opening 18, of the chamber 16, is located insubstantially a horizontal plane with the bottom of the vessel, it isapparent that said chamber and pipe will form a positive trap, as wellas a water seal, thus preventing the escape of gases from the sewerthrough the pipe 26, and its connections with the vessel. Instead ofemploying the detachable weights 23, on the valve stem 20, for thepurpose of regulating the liquid pressure required to operate the'valve,a contracting sprin'g29, surrounding the upper-portion ot' the stem 20,and secured at one of its ends to a portion of the stufling box 21, andat its other end to a nut 30, in screw engagement with thestem 20, (seeFig. 4,) may be employed, in which operation it is evident that thevalve 19, will be pressed downwardly and firmly held in its seat by theaction of the spring 29, and that by loosening or tightening the nut 30,on the stem, the tension of said spring may be regulated so as torequire more or less liquid pressure to operate the valve.

In Fig. 2, is shown a modification in the which consists in employing avalve casing 12, having upper and lower chambers 15, and 16,respectively, and divided by a horizontal'or transverse partition 17 asin the other construction. In this'modified form of the valve, thepartition 17 is provided with an upwardly ta pered opening or valve seat18, for a correchamber 15, pipe 16; and the valve 19 spondinglytaperedvalve 19, the stem 20, of which, is extended through a stutfing-box 21,on the upper portion of the valve casing, and has above thestufling-box, a pin or'projection 31, to fit in a slot 32, formed in oneend of a lever 33, which is fulcrumed on a suitable support 34, mountedon the upper part of the valve casing or otherwise. Adjustably mountedon the outer portion of the lever 33, is a weight 35, which will holdthe valve 19 in its raised or seated position until the liquid pressurecontained] the 11, and vessel, is suflicient to overcome the weight 35,when it is apparent that the valve 19, will be lowered to about'theposition shown by dotted lines in Fig. 2, thus permitting the liquid topass from the chamber 15, through the opening 18, into the chamber 16,and from thence out through the conduit 24, and drain pipe to the sewer.In this modified construction, it will be observed that the pipe 11, isconnected to an extenslon 13, having communication with the upperchamber 15, instead of the lower chamber 16, as in the otherconstruction, and that the conduit 24, has direct communication with thechamber 16, instead of with the chamber 15, as in the first describedform of the valve.

In Fig. 3, is shown still another modification in the construction ofthe valve, which consists in employing a casing of similar constructionto that shown in Fig. 2, and just above described, that isto say, thepipe 11, has communication through an extension 13, with the upperchamber 15, while the conduit 24, leads'from the lower chamber and itsseat 18", is upwardly tapered, and adapted to We operated by thedownward pressure oft-he liquid.

In this modification, an expanding spring 36, surrounding the valve stem20, above the stufling-box 21, and resting at one of its ends oneportion of the stuifing-box, and at its other end against a nut 37, inscrew-engagement with the stem 20, is employed to hold the valve in itsraised or seated position, and against liquid pressure in the vessel,pipe 11, and upper chamber 15, of the valve casing. As the nut 37 isadjustable on the stem 20, it is apparent that the tension of the spring36, may be regulated so as to require more or less liquid pressure tooperate the be extended upwardly for any considerable distance and maybe provided at its upper portionwith a knob or any desired means bywhich the rod and valve may be operated manually.

From the foregoing and by reference to the drawing, it will be apparentthat the device is susceptible of considerable modification withoutmaterial departure from the principle and spirit of the invention, and

or this reason I do not desire to be un-. derstood as limiting myself tothe precise form and arrangement of the .several parts of the device asherein set forth in carrying out my invention in practice. I
